ESTIMATION OFAIRBORNE RADIOACTIVITY INDUCED BY 8-GEV-CLASS ELECTRON LINAC ACCELERATOR

摘要

Airborne radioactivity induced by high-energy electrons from 6 to 10 GeV is estimated by using analytical methods and the Monte Carlo codes PHITS and FLUKA. Measurements using a gas monitor with a NaI(Tl) scintillator are carried out in air froma dump room at SACLA, an x-ray free-electron laser facility with 7.8-GeV electrons and are compared to the simulations.
